WORK-SUPPORTING MECHANISM.

Specification of Letters Patent. Patented J an 18 1921 Application filedMarch 11, 1918. Serial No. 221,719.

To all '11) ham it may concern:

Be it known that we THOMAS Soorr and JAMES E. CLELAND, subjects of theKing of England, residing at Montreal, in the Province of Quebec andDominion of Canada, have invented certain Improvements in\Vork-Supporting Mechanisms, of which the following description inconnection with the accompanying drawings, is a specification,likereferenee characters on the drawings indicating like parts in theseveral figures.

This invention relates to work supporting mechanisms for fasteninginserting machines and more particularly concerns the means foradjusting the work supporting means relatively to the fasteninginserting mechanism of such a machine.

Inthe operation of fastening inserting machines, it is most essentialthat the work be presented in exact relation to the fastening insertingmechanism both as regards the maintenance'of the work against the footplate of the fastening inserting machine to steady the work, and toinsure the driving of the fastenings completely into the work and asregards the arrangement of the work laterally of the plane ofjoperationof the fastening inserting mechanism to cause the fastenings to bepositioned properly in the work. In order to maintain work of differentthicknesses in proper position for operation of the fastening insertingmechauism thereon, the work supporting means must be adjustedvertically. On the other hand, to the end that work of varying forms maybe so arranged relatively to the point of insertion of the fasteningsthat the fastenin s willbe rightly placed in the work and that the workmay he sustained firmly under. the impact of the fastening insertingmechanism, adjustment of the work supporting means laterally of theplane of operation of the fastening inserting mechanism must be made.Since the character of the work upon which fastening inserting machinesare called upon'to operate diflers very greatly as to thickness andform, it is imperative that the means for supporting the work have awide range and great delicacy of adjustment so that by adthe horn.

justment of the work supporting means variations in thickness and formof the work may be compensated for and the work presented to thefastening inserting mechanism in the exact position which it shouldoccupv relatively to said mechanism. Moreover, since the fasteninginserting mechanism imparts a heavy blow upon the work in the insertionof the fastenings, it is essential rigidly under the blow imparted bythe fastening inserting mechanism. In accordance with a further objectof the invention, the structure wherein the invention is embodied ismade simple in construction and convenient and sensitive in operation.

An important feature of the invention resides in the provision of meansfor adjusting the horn longitudinally of the horn post comprisingcooperating parts carried by the horn and the horn post and constructedand arranged to permit rotary movement of the horn on the horn post andto maintain the horn in a fixed position of adjustment longitudinally.of the horn post regardless of rotary movement of The horn is providedwith a work supporting surface adjustable laterally ofthe of the hornpost by rotary movement of the horn on the horn post so that the worksupporting surface can readily be adjusted either axially oreccentrically of the horn post.

The invention further contemplates the provision of means for securingthe horn in adjusted position on the horn post of a character such as tobe operated preceding or subsequent to the adjusting of the horn on thehorn post with the utmost ease and -quickness to release the horn formove ment or to lock it in adjusted position, a

member manipulable by the operator to adjust the horn longitudinally ofthe horn post without rotating it or to move the iorn simultaneouslyboth longitudinally and rotatively relatively to the horn post, andmeans for indicating to the operator the relative arrangement of thehorn longitudinally of the horn post.

Still other objects and features of the invention will be apparent asthe description proceeds.

in the drawings,-

Figure 1 illustrates a portion of a fastening inserting machine equippedwith worl: supporting mechanism made in a cerdance with the invention,

3 is a View in elevation of the work supporting mechanism partly incross section along the line 3-3 of F 2 looking in the direction of thearrows.

The invention is disclosed by way of example as associat-d with afastening inserting machine of the type described in the United StatesLetters Patent to Gasgrain No. 1,011',381 granted February 13, 1912,said machine comprising a frame 2 carrying a head elupon which ismounted fastening, inserting mechanism 6 operated from the main shaft 8.The frame 2 is further provided with an upstandinghollow projection 10in which is slidably mounted the horn post 12 which carries the worksupporting mechanism by which the work is held in operative relationwith the fasteninginserting mechanism 6 during the insertion of thefastenings into the work. The above-mentioned elements constitute inthemselves no part of the present invention, for which son a furtherdescription thereof is deemed unnecesary.

In the present instance of the invention the horn post 12 is formedadjacent to its upper end with annular grooves 1 2: alternating withannular corrugations or teeth 16, and a horn 18 comprising a sleevedportion or member 20 and a horn spindle 22 is mounted on the upper endof the horn post the sleeve 20 of the horn being fitted loosely on thetoothed upper end of the horn post in such manner as to be freelymovable bot-h longitudinally and rotatively relatively to the horn post.1

Means are preferably provided for neting the horn 18 vertically on thehorn post and, in the illustrated embodiment of the invention, suchmeans comprises a pinion stud 24 journaled in a boss 26 formed on thesleeve 20, the teeth of the pinion being constructed and arranged forengagement with the corrugations or teeth 16 of the horn 7 post. Thepinion stud 24 has provided thereon at one end the hand wheel 25% formanipulation by the operator in cli'cctiup; the adjustment of the horn.

it is nioreovmr desirable that the operator should be able to determinereadily the exact position of adjustment of the horn 18 on the horn post12. In the present instance of the invention the operator is enabled soto do by means of an indicator disk or scale 30 carried by the sleeve 20of the horn and a finger 32 carried by the end of the pinion stud 2dpposite the hand wheel 28 and 111' ranged for movement over the face ofthe indieator disk 30.

In order that the sleeve 20 of the horn, which, as before stated, isconstructed to slide freely on the horn post, may be maintained in anyposition to which it may be adjusted, means are provided fo securing itagainst movement relatively to the horn post. As illustrated, the sleeveis secu ed in position on the horn post by nica T of a handled set sc ew3-11: having formed thereon an annular enlz genient or shoulder iifsaidscrew being a lapted to pass loo lv through an car 38 formed on thesleeve 21) at one side of a slit 4;!) and to be threaded into aninternally threaded opening foruod the car 4-2 at the other side of thcslit 10. Referring to Fig. 2, it will be evident that when the screw isthreaded into the opcuing in the ear 4-2 the shoulder ill; o the screwwill engage the our 351 of the sleeve and the cars -38 and 42 will bcdrawn togethe in such manner as to loci; the 2 y on the horn post Thehandle 1 of the so cw Sel- (Fig. 2) is arranged on the horn postoppositely of the hand wheel 28. Consequently the operator mayconveniently grasp the handle 3; and the milled nut 28 with his hands atthe some tune and is thus enabled, with the 'rcatcst possible ease,accuracy, and despatch, to adjust the horn to any desired position asdetermined by inspection of the indicator which is so located to bereadily iuspcclcd by the operator while manipulating; the haudle 353 andnut 28, and to secure the horn in adjusted position on the horn post.

Means are also provided for adiustin ix e horn spindle 22 and the horntip carried thereby relatively to the axis of the horn post 12. Asshown, said means comprises stud 4L6 socketed in the upper end of thesleeve 20 eccentrically of the axis of the sleeve and of the horn post.

it, will he Ollvious from the foregoing that the spindle 22 and tip ofthe horn may be adjusted relutively to the axis of the horn post byangular or rotative movement of the sleeve 2f) about the horn post. itwill be further noted that by reason of the annular corriuratirms in thehorn post the sleeve 20 of the horn may be rotatively moved on the hornpost lit) lll

without affecting the position of longitudinal adjustment of the horn onthe horn post, since, when the sleeve 20 is moved angularly on the hornpost, the teeth of the pinion stud 24 travel in the grooves 14 of thehorn post. It will further be apparent that by the constructionhereinbefore described the horn 18 may be adjusted both longitudinallyand rotatively relatively to the upper end of the horn post and may belocked in adjusted position by the handled set screw 34. i oreover, thearrangement of the parts is such that the operator, by manipulation ofthe hand wheel 28 in the direction of the length of the pinion stud 24at the same time that he turns the wheel, may simultaneously effectboth. rotary and longitudinal adj ustments of the horn on the horn post.

If the horn tip 44 were mounted eccentrically of the axis of the sleeve20 and horn post 12 without capacity for adjustment relatively to theaxis of the horn post, it would follow that the adjustment of the horntip 44 would be limited to a circular path about the axis of the hornpost. In

order, therefore, to permit universal adjustment of the horn tip 44 onthe horn post, the stud 46 by which the horn spindle 22 is connected tothe sleeve 20 is arran ed eccentrically of the horn spindle 22 and horntip 44 to a degree substantially equal to the eccentricity of the studrelatively to the axis of the horn post 12. It follows, therefore, thatby angular movement of the horn spindle 22 and the stud 46, the axis ofthe horn spindle and of the horn tip 44 may be alined with the axisofthe horn post. Obviously when the horn spindle and horn tip are sorelated to the axis of the horn post, angular movement of the sleeve 20about the horn.

post will not chan e the relation of the horn spindle 22 and orn tip 44to the horn post. If, however, the horn spindle 22 and stud 46 areturned to a position such that the axis of the horn spindle is slightlyoffset from the axis-of the horn post, angular or rotative movemnt ofthe sleeve 20 about the horn post will effect adjustment of the horn tiprelatively to the axis of the horn post, and it will be further apparentthat, by adjustment of the horn spindle 22 and stud 46 relatively to thesleeve 20 and of the sleeve 20 angularly of the horn post, the horn tip44 and horn spindle 22 may be moved to any position within a range ofmovement defined by a circle having the axis of the horn post as acenter and a radius equal to the sum of the distances by which the axisof the stud 46 is offset from the axis of the horn post and by which thehorn spindle 22 and horn tip 44 are offset from the axis of the stud 46.As shown, the horn spindle 22 is secured rotatably to the sleeve 20 by ascrew or the like 48 engaging in an annular groove 50 formed in theperiphery of the stud 46 adjacent to its lower end.
